Rationalise debugger stuff in the tree.
Within Xen itself, remove PDB references and fold into domu_debug.
When domu_debug hits a breakpoint, it pauses all vcpus of the domain
and raises VIRQ_DEBUGGER (not VIRQ_PDB). The debugger in domain0 can
either poll pause status or bind to VIRQ_DEBUGGER. Before debugging
a breakpointed domain the debugger should issue PAUSEDOMAIN itself, or
it is not guaranteed to see paused state of the domain!
Outside Xen there's a new dir tools/debugger, containing gdb, pdb and
a new library libxendebug (used by pdb). I also think the ptrace
functions in libxc also ought to be moved out: either to libxendebug
or to a new library libxenptrace.

[PATCH] [PATCH] libxc: mmap doesn't return NULL on error...
Hi, was reading libxc code, and noticed this. Patch is bigger than
strictly necessary due to indent adjust.
Against latest bk.

Batch p.t. pin requests during guest restore (after being suspended, or
after migration). Allow L1 tables to be pinned even after their va
backptr is fixed (no longer mutable).

Split mmu_update() hypercall into mmu_update() and mmuext_op().
All MMUEXT_* ops are now done via the latter hypercall. This allows
more arguments to be passed in a nicer way to mmuext operations.
Linux 2.4, 2.6 and control tools all use the new interface. The BSDs
will need some work, but shouldn't be too hard (and they can be moved
to writable pagetables at the same time :-) ).

The getdomaininfo hypercall now listens to the exec_domain parameter
that was already passed to it, and performs some basic sanity checking.
Added exec_domain (aka vcpu) parameters to xc_domain_getfullinfo()
and xc_domain_get_cpu_usage().
Code duplication cleanup: remove a number of duplicate identical
static functions in xc_*_{build,restore}.c, replaced with single
(non-static) copy in xc_private.c
